compiled js files and ts compiler config

[harterc3]

Added tsconfig.json file and included compiled ES5 js files since people were asking for it to be included in git repo.

Thanks for the PR!

I appreciate the pull request however i'm not entirely sure this will work with the npm package.
The package itself is only the src/lib folder to reduce the package size, so the corresponding files need to be added to src/lib/dist and a tsconfig.json to be able to be installed with the npm package

@AnteWall Thanks for the feedback! Good point on the lib folder. I put another commit in for compiling to lib/dist instead. Let me know if there is anything missing.

@harterc3 Looks good to me! Will merge and update the package during the day, thanks a lot for the PR!
